Patent GB-2085820-A (GB)
Title: Aircraft with variable strakes
IPC: B64C9/34
Filed: 1980-09-09
Abstract: An aircraft having strakes 13 has the strake area variable (for control at high angle of attack) either overall or by disposition (by, for example, increasing a strake's span and decreasing its chord). As shown, each strake has a fixed portion 13a and a movable portion 13b which may retract into the fuselage 11 or the fixed portion 13a, or may be moved to overlie or underlie the fixed portion. The strakes may be adjusted symmetrically for pitch control, or asymmetrically for roll, yaw, and side force control in addition to pitch. Parts 13b can be automatically locked during flight at low angles of attack. <IMAGE>

Title: A device for locating a submerged submarine
IPC: G01V3/08
Filed: 1980-10-13
Abstract: A device for locating a submerged submarine includes a magnetic device supplying a magnetic field for adherence of the device against the external structure of a submarine, the magnetic device comprising at least two magnets 2, 3 located adjacent to each other and having co-acting magnetic fields, and a magnetically operated switching means 4 within the magnetic field provided by the magnets, the switching means being responsive to a change in the magnetic field due to the introduction of a metal mass into the field to actuate a source 11 of an acoustic signal. One pole of battery 7 is attached to metal plate 12 which is insulated from the casing 6 by acoustic source 11 until the device is itself immersed, thus obvious premature triggering of the sonar device. <IMAGE>

Title: Video interphone station
IPC: H04M11/02
Filed: 1981-04-13
Abstract: A remote station, which may be located at a door of a house, is provided with a television camera for use with a master station, which may be located in the house, of an inter-communication system.

Title: A structure-patterned knitted fabric and a knitting machine mechanism for its production
Inventor: PLATH ERNST-DIETER
IPC: D04B9/38
Filed: 1984-07-25
Abstract: By controlled adjustment of cam box parts 22 the needles 11 are influenced collectively whilst avoiding individual needle selection to produce pattern regions with varying stitch length. The formation of particular patterns is effected by the choice of the shape of cams 14', 15' on two or more cam carriers, 14, 15 which rotate relative to the cam-box carrier 21, by the choice of the direction of movement of these cam carriers 14, 15 relative to the needle cylinder 10, and by the choice of the ratio of the magnitude of movement of the carriers 14, 15 to that of the needle cylinder 10. In the latter respect, programme-controlled individual drive of the individual cam rings 14, 15 can be effected or they may be geared at 18 to the needle cylinder carrier 12. The pattern may take the form of stripes which can cross over, zig zag or have curved regions. <IMAGE>
